High-performance sonic drilling: clean, fast, and reliable results

At 403 Drilling, we utilize advanced sonic drilling technology to deliver superior core recovery, faster penetration rates, and cleaner boreholes for projects across Canada.

Our sonic rigs provide unmatched accuracy and efficiency, making them suitable for geotechnical investigations, environmental assessments, mineral exploration, and groundwater studies, regardless of ground conditions.

Advantages of Sonic Drilling

Sonic drilling employs high-frequency mechanical vibrations to advance a core barrel or casing through the subsurface. These vibrations temporarily reduce friction between the drill string and the surrounding material, enabling rapid penetration through unconsolidated formations like sand, gravel, and till without the need for drilling fluids.

  • Reduced Risk of Cross-Contamination

    Sealed casing advancement ensures sample integrity.

  • Cost-Effective Data Collection

    Higher accuracy means fewer holes and better results.

  • Faster Penetration Rates

    Complete boreholes in a fraction of the time of conventional drilling.

  • Low Environmental Impact

    No mud, no mess: ideal for sensitive or contaminated sites.

  • Exceptional Core Recovery

    Up to 100% continuous core samples in all soil types.
